PROCESS F :MAKINGV NARROW-WIDTH WIRE vFLHY-SCREENl CLOTH.

To all it'mdy concern:

B e it known that I, WILLIAM'F. Hannan, a citizen of the United-States,residing at Niles, in the county of Berrien and State of Michigan, haveinvented a certain new and useful Process of Makin Narrow- W'idth Wire`FlyScreen Cloth; and I do hereby declare the following to be a full,clear, and exact description of the same, reference being had to theaccom an'ying drawings, forming-part of this specification, and to thefigures and letters of. reference marked thereon.

In. the manufacture of wire screen cloth commonlydesignated as iiyscreen cloth, it

is found that the cost of manufacturing narrow widths is practically thesame as the cost of manufacturing wide widths, except for theAdifference in the quantity of the material'e1nployed;,that is to say,the time and power required are practically the same, and iconsequentlytiooms for, the weaving of this character 'of material are;ordinarily made of a size to weave cloth of a standard wide width, andwhen narrow cloth is to be woven, a smaller number of warp wires areemployed, the other parts of the mechay manufacture of wide wi tbs.

nisxn being correspondingly set for the width to be woven.'` l

The object ofthe present invention is to provide a process ofmanufacture which may be practised without change in the ordinaryequipment, but which will result in the production of two or more widthsof narrow screen cloth with the expenditure ofy no greater time or powerthan inthe lproduction of single narrow widths,l and without requiringreadjustment or setting of the parts of the mechanism different from theadjustment or settin employed in the To the above ends, the inventionconsists,

l broadly stated, in weaving the'fly screen cloth in a single widthwhich is equal to the combined widths of a plurality of the y hfinallysevering the cloth into the desired narrow widths by cutting the weftwires in the space between the selvages and winding' I `Specication. ofLetters Patent.

the narrow widths separately from each other.

Referring to the accompanyin draw 1ngs,-Figure 1 is a perspective viewdiagrammatic in character, of a section of wire fly screen clothillustrating the .process of manufacture. Fig. 2 is a diagrammaticillustration of the mechanism preferably employed in the manufacture ofthe cloth.

l/Vire screen cloth of the vcharacter referred to is formed by warp andweft wires which are spaced apart a distance to form openings of thedesired size, and in accordance with the process of the presentinvention, a suiicient number of warp wires are employed to form a clothwhich will be in width equal to a plurality of the narrow width desired.As illustrated in the drawing, the cloth is woven double the widthdesired and, while one integral width, is subjected to the coating anddrying steps of the process. ln Fig. l, the portion of the cloth at A issupposed to be that portion which is delivered from the weaving -loom,and it will be noted that at the center or middle portion, spacedselvages are formed by bringing two warp wires close the weft wires onopposite sides and in substantially ,the same plane, but with wirecloth, a severing of the two narrow widths at this stage would beimpractical, because of the likelihood of the warp wires slip-l ping onthe weft wires and resultingv in an lmperfect product. To prevent thisresult, the screen cloth is coated with a coating which will at the sametime protect the wire and also serve as a means to cause the warpselvage wires and the weft wires to adhere to each other, this stage ofthe process being indicated in the drawing at B. This coating is driedas indicated at C, and inallythe narrow widths are separated by Severinthe weft wires in the space l between t e inner selvages, as at D, forwhich pur ose rotary cutters d, Fi 2, may be goyed, and immediately tereafter,` the two narrow widths are .separately rolled, as at E, andprepared for the market.

The narrow widths of-screen clothv prepared as described in accordancewith thisv conditions and use. The edge furthermore;

is stiened and will -be more irmly held in line,. asvfcreizample, wheretacked into screens with the'tacks spaced a considerable distanceapart.`

In the manufacture yofnarrcw width fly screen cloth inacccrdance withthis invention no change lin the ordinary equipment is requiredl-savethe introduction ofthe. cutters in such position or relation tothe otherparts ofthe plant thaty the cloth may be split into ythe narrowwidthsater they coating and drying stages of the operation,

and preliminary to the winding Aof the widths into rolls. v

Practice demonstrates that: the process results in a very materialsaving to the manuf facturer, the only additional materialrequired-being one extra warp wire which is introduced to form one of'the selvage wires on one side of the space,A vthe wire which wouldnormally occupy said space being moved over to'form the v extra erselvage warp wire of the other width. Obviously more than two narrowwidths with separating selvages may be woven at one time and the narrowwidths may be of equal or un-l equal width as desired.

Having thus described my invention, what I claim as new and desire tosecures/by Letters Patent of the United States is,-f-'

1. The improved process of making narrow width wire Hy screenclotlnwhich consists in weaving the screen cloth in a single websubstantially equal in width to the combined widths of a plurality ofthe desired narrow widths, and with spaced inner selvagesseparatingthe'web into they narrow widths, said selvages being formed bywarp 'wires woven close together to grip the weft wires on. oppositesides insubstarr tially the same plane, then applying a coating to cause4the selvage warp and weft wires to adhere to each other, and finallysevering the Ycloth into the desired 'widths by cutting the weft wiresin the space between the selvages .formed by the closely weven warpwires.

2. The improvedv process of making narrow width wire y screen cloth,which consists in weaving the screen cloth in a single webVsubstantially equal in width to the combined widthsr of a pluralityofthe desired narrow widths, omitting a warp wire to Vform the spacebetweenthe narrow widths5 introducing additional warp wires on each sideof said space to form selvagcs which grip the weft wires on oppositesides. in substantially the same plane, then applymg acoating to causethe selvage warp and the weft wires to adhere Vto each other, thendrying said ccating, then severing the cloth into the desired narrowwidths, by cutting the weft wires in' the space between the selvagesfrom which the warp wire was omit ted, and finally winding the narrowwidths separately from each other. n WLLIAM F. fHARRAH.
